In Python3+ print is a function so the old syntax is not correct
anymore:
$ ./scripts/bloat-o-meter vmlinux.o vmlinux.o.old
File "./scripts/bloat-o-meter", line 61
print "add/remove: %s/%s grow/shrink: %s/%s up/down: %s/%s (%s)" % \
^
SyntaxError: invalid syntax
Fix by calling print as a function.
Tested on python 2.7.11, 3.5.1
